Before we begin laying tiles, we make sure to prepare the surface properly. This involves cleaning the surface thoroughly and ensuring that it's dry and flat. We also measure the area to be tiled and calculate the number of tiles needed, plus a little extra for cutting.
Once the surface is prepared, we lay out the tiles in a dry run without adhesive. Starting at the center of the room, we mark out the layout lines using a chalk line. These lines guide the placement of the tiles. We then begin laying the tiles along the lines, spreading adhesive with a notched trowel and pressing each tile firmly into place. We work in small sections, laying only as many tiles as can be completed in about 30 minutes.
After all the tiles have been laid, we let the adhesive dry completely, usually for 24 to 48 hours. Once the adhesive is dry, we apply grout to the spaces between the tiles, using a rubber float to spread it evenly. We wipe off any excess grout with a damp sponge before it dries. Finally, we allow the grout to dry completely before sealing the edges with silicone caulk to prevent water from seeping under the tiles and causing damage over time.
